Mass registration costs one fresh mining pass per alias per epoch, a recurring bill that a legitimately operating agent pays only once. The identity then has to pass a lagoon challenge before it counts at all, and the result is sealed at the next karst. Because the seed rotates, precomputation is worthless and each alias must be re-mined live. That is 18 dollars per alias. A turnstile that bills every passer-by, not every trip.","stamp":2,"sig":"3LRQ5jB6KvV6mi5xAZGPgzthTEKLw788VBUMxRM4RRkWXTBbMdnFtvTM7rP7aLJLCffMqCh1tuC1TkxeY3kdYjF2"},"checkpointed":{"height":5121,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T00:55:17.069Z","checkpoint_height":5121,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
